Anaerobic & Necrotizing Infections

Description of Medical Condition Gangrene is local death of soft tissues due to disease or injury and is associated with loss of blood supply.

Specific Anti-Infective Agents

Antibiotics Before prescribing a specific antibiotic, clinicians should be able to answer these questions: •  How does the antibiotic kill or inhibit bacterial growth? •  What are the antibiotic’s toxicities and how should they be monitored? •  How is the drug metabolized, and what are the dosing recommendations? Does the dosing schedule need to be modified in patients with renal dysfunction? •  What are the indications for using each specific antibiotic? •  How broad is the antibiotic’s antimicrobial spectrum? •  How much does the antibiotic cost? Clinicians should be familiar with the general classes of antibiotics, their mechanisms of action, and their major toxicities. The differences between the specific antibiotics in …

Antimicrobial therapy: general principles

A wide variety of antimicrobial agents is available to treat established infections caused by bacteria, fungi, viruses, or parasites. This section will cover the general principles of antimicrobial therapy and will also include illustrative clinical problems to emphasize proper decision-making in using antimicrobials. Determinants of Antimicrobial Efficacy Measurement of antimicrobial activity in vitro Susceptibility testing is indicated for any bacterial pathogen warranting chemotherapy. Drugs that irreversibly destroy the ability of an organism to replicate, and perhaps in the process destroy the structural integrity of the organism, are microbicidal. Drugs that reversibly impair replicating ability, with this function being restored when drug concentrations fall below critical inhibitory levels, are microbiostatic. In quantitative …

Cefoxitin Sodium

• Cefoxitin is a semisynthetic cephamycin b-lactam antibiotic. Uses Cefoxitin is used in the treatment of serious infections of the lower respiratory tract, skin and skin structure, bone and joint, and urinary tract; septicemia; gynecologic infections (including endometritis, pelvic cellulitis, and pelvic inflammatory disease); and intra-abdominal infections (including peritonitis and intra-abdominal abscess) caused by susceptible bacteria. Cefoxitin also has been used in the treatment of uncomplicated gonorrhea and is used for perioperative prophylaxis. Prior to and during cefoxitin therapy, the causative organism should be cultured and in vitro susceptibility tests conducted. In serious infections, therapy may be initiated pending results of in vitro tests. Use of cefoxitin does not replace surgical …
